BACKGROUND OF THE INVENTION 1. Fields of the Invention 2. Descriptionsof Related Art

There are many different types of hiking shoes that have differentfeatures for different trail conditions. Most of the trails in theforests have pebbles which can make conventional hiking shoes fail toprotect the wearers because the pebbles reduce friction between thehiking shoes and the paths of the trails, especially in rainy days. Somehiking shoes have spikes protruding from the outsole such that thespikes bite into the soil and provide better friction. However, thesesspikes cannot perform as desired because pebbles rolls and small insize, spikes cannot penetrate through the pebbles to grab the shoes inthe trail paths. The pebbles are easily stocked between spikes to affectthe effective length of the spikes so that the spikes cannot bite intothe soil.

The present invention is intended to provide a hiking shoe that hasanti-slip blocks, and spikes are embedded in some of the anti-slipblocks. Each spike includes specific grooves in the distal face thereofto provide better anti-slip features.

SUMMARY OF THE INVENTION

The present invention relates to a hiking shoe and comprises a vamp andan outsole. The outsole includes a rear section and a front section. Theoutsole has multiple anti-slip blocks formed thereto, and the anti-slipblocks are located at a distance from each other. Multiple spikes arerespectively and integrally formed to a portion of the anti-slip blocksthat are located at the rear section and the front section of theoutsole. Each spike has an end face that is formed on the first endthereof, and the end face is in flush with the distal end of theanti-slip 16 corresponding thereto. The second end of each spike islocated within the anti-slip block corresponding thereto and within theoutsole. The end face of each spike has multiple grooves definedtherein. Each spike is made by SKD-11 (Steel Kogu Dies-11). The groovesof the spikes are configured to provide friction.

Preferably, the front section of the outsole includes a first area and asecond area. A bending line is defined between the first and secondareas. The bending line is formed when a heel of the shoe lifts up. Theanti-slip blocks that are located on the bending line each have one ofthe spikes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 7, the hiking shoe 1 of the present inventioncomprises a vamp 11 and an outsole 12. The vamp 11 is located above thetop of the outsole 12 and connected along the periphery of the outsole12. The vamp 11 includes an opening 14 and a trim portion 15, whereinthe trim portion 15 is located along a portion of the opening 14. Theopening 14 is configured to accept insertion of wearer's foot. Theoutsole 12 includes a rear section 131 and a front section 132. Theoutsole 12 has multiple anti-slip blocks 16 formed thereto, and theanti-slip blocks 16 are located at a distance from each other.

Multiple spikes 2 are respectively and integrally formed to a portion ofthe anti-slip blocks 16 that are located at the rear section 131 and thefront section 132 of the outsole 12. The spikes 2 are integrally formedwith the anti-slip blocks 16 so that the spikes 2 are not separated fromthe anti-slip blocks 16. Each spike 2 has an end face 20 that is formedon the first end thereof. The end face 20 is in flush with the distalend 160 of the anti-slip block 16 corresponding thereto. The second endof each spike 2 is located within the anti-slip block 16 correspondingthereto and within the outsole 12. The end face 20 of each spike 2 hasmultiple grooves 21 defined therein. In this embodiment, the grooves 21are formed in a netted pattern. Each spike 2 is made by SKD-11 (SteelKogu Dies-11). The grooves 21 of the spikes 2 provide friction when thegrooves 21 are in contact with small rocks or pebbles so as to obtainanti-slip features. The SKD-II is an alloy that includes higherpercentage of Carbon and Chromium, and has high stiffness and durable.The SKD-11 has great wear-resistant feature and has less deformationafter being quenched. The hardness can reach to HRC58-62 degrees. TheSKD-11 has acceptable price and is widely used as molds. The SKD-11 isone of the best alloy which is durable and not deformed. The crystals ofthe SKD-11 are fine and pure after secondary refining. Therefore, thespikes 2 made by SKD-11 allow the hiking shoes 1 to have betteranti-slip function.

Specifically, the front section 132 of the outsole 12 includes a firstarea 1321 and a second area 1322. A bending line “A” is defined betweenthe first and second areas 1321, 1322. The bending line “A” is formedwhen the heel of the hiking shoe lifts up. The anti-slip blocks 16 thatare located on the bending line “A” each have one of the spikes 2. Eachof the spikes 2 includes a head 22 and a shank 23. Each of the anti-slipblocks 16 that has the spike 2 formed therein has a recess 121 definedtherein. The recess 121 is defined in the outsole 12 as well. The spike2 is integrally formed in the recess 121 corresponding thereto duringmanufacturing processes. Each recess 121 includes a large-diameter area122 and a small-diameter area 123, wherein the small-diameter area 123is located in the anti-slip block 16 and the outsole 12 correspondingthereto, and the large-diameter area 122 is defined in the outsole 12.The head 22 of the spike 2 is formed within the large-diameter area 122corresponding thereto, and the shank 23 of the spike 2 is formed withinthe small-diameter area 123 corresponding thereto so as to prevent thespike 2 from dropping off from the recess 121.

The rear section of the outsole 12 includes a third area 1311 and afourth area 1312. A separation line “B” is defined between the third andfourth areas 1311, 1312. The separation line “B” passes through two ofthree spikes 2 and the two spikes 2 are located in the anti-slip blocks16 of the rear section 131. The third area 1311 includes a flat section133 and a curve section 134. The third one of the three spikes 2mentioned above is located in the curve section 134. The two spikes 2that the separation line “B” passes and the spike 2 that is located inthe curve section 134 are located at three points of an imaginarytriangle.

The three spikes 2 that form a triangle on the rear section 131 of theoutsole 12 provide sufficient contact area with the ground. When thegrooves 21 of the spikes 2 that are made by SKD-11 contact the rocks orpebbles, the spikes 2 do not slip so that the wearer wearing the hikingshoes 1 do not slip.

FIGS. 8 to 10 show another embodiment of the present invention, whereinthe difference from the previous embodiment is that the end face 20 ofeach spike 2 has a notch 200 defined therein, and the grooves 21 extendradially from the periphery of the notch 200 and communicate with thenotch. The notch 200 and the grooves 21 perform as a pawl to grab therocks so that the wearer wearing the hiking shoes 1 do not fall even onslippery rocks.

When the rear section 131 contacts the trail path, the rear section 131has the maximum contact area with the trail path, so that the threespikes 2 arranged as a triangle can obtain the best anti-slip feature.Furthermore, when the heel of the hiking shoe 1 is about to lift and thefront section 132 of the hiking shoe 1 is about to contact the trailpath, the spikes 2 on the rear section 131 prevent the wearer fromslipping if the rear section 131 contacts pebbles. The spike 2 locatedat the curve section 134 ensure the walking in a stable status. Thespikes 2 that are located at the three points of the triangle can ensureat least one spike 2 to contact the trail path in any situation.

While we have shown and described the embodiment in accordance with thepresent invention, it should be clear to those skilled in the art thatfurther embodiments may be made without departing from the scope of thepresent invention.
